Construction of a Pentagon on the cube Proof of Part I: Pentagon is Equilateral Proof of Part II: Pentagon is in One Plane Proof of Part III: Pentagon is Equiangular Proof of Part IV: Side of Dodec Form Apotome Construction of the Dodecahedron

By connecting all the points extended by the Cube-to-Pentagon Connection Lines and 2 corners of the cube, we apparently obtain a pentagon. The next part of the proof will show that this is a regular pentagon.
